Title: Device for introducing and removing push-in parts into or from cooker baking ovens
Inventor: LUENENBUERGER WALTER
IPC: F24C15/16
Filed: 1985-02-18
Abstract: In a simple and economical manner, the invention solves a problem of cooker baking ovens which has existed for years (see illustrations 3+4+5). Accordingly, movable slides (6), which are mounted in the baking oven (1) and in which the baking oven push-in parts (8) are guided, can now be moved forwards and backwards in such a manner that, in the position (illustration 5) in which they are pulled out from the baking oven (1), they still support the push-in parts (8) perfectly, which are then situated with their entire working surface in front of the baking oven front wall. In hot-air baking ovens, even with simultaneous use of a number of baking oven push-in parts, these can thus be pulled individually out of the baking oven (1) with baking carriage effect. The member, which takes the slides (6) along with it, is designed as a heat-resistant spring (10). The springs (10) are supported on functionally corresponding running surfaces (11) and engage in catches (13) which are provided on the push-in parts (8). At predetermined places (14), the spring (10) releases the push-in part (8) so that it can be removed completely from the baking oven (1). If the slides (6) are arranged e.g. on existing baking oven push-in grates (4), the device can be removed particularly easily from the baking oven (1) for convenient cleaning. <IMAGE>

Title: Method of threading strings of pearls and corals and a device for carrying out the method
Inventor: HALL FRIEDRICH
IPC: A44C11/00
Filed: 1985-02-22
Abstract: The invention relates to a method of threading strings of pearls, corals or the like and a device for carrying out the method. Pearls (17) threaded onto double threads (16) to form individual strings are placed adjacently in a predetermined length, the ends of the double threads (16), forming a loop, being hooked individually into hooks (7' to 12') of the device and the free ends of the double threads (16) being attached permanently to a fixed point. When the device has been switched on, the pearls (17) are moved back and forth by hand on the twisting double threads (16). After reaching the given number of rotations or the required degree of twisting of the individual double threads (16), all the pearls (17) are moved toward the fixed point (19 or 20) and, whilst retaining the combination of all the twisted double threads (16) at the end (22), the double threads (16) are cut off at the hooks (7' to 12') and knotted together. The knotted end (22) continues to be fastened and the jointly twisted double threads (16) at the fixed point (19, 20) are released and knotted together at the end (21). Only then are the knotted ends (21, 22) released and the individual strings spring together to form a completely threaded chain which will no longer open. By means of the device, the same number of revolutions is applied individually to each individual string. <IMAGE>

Title: Method and device for controlling the ultrafiltration in blood purification methods, especially in haemodialysis
Inventor: POLASCHEGG HANS-DIETRICH DR
IPC: A61M1/36
Filed: 1985-07-11
Abstract: In a method of controlling the ultrafiltration, blood plasma is filtered out of the extracorporeal circulation and its conductivity is determined. Plasma water or haemofiltrate is then separated off the blood plasma and has its conductivity likewise determined, and thereafter the volume of the fluid withdrawn is determined from the difference in conductivity. This results in the advantage that the parts of the device (1), according to the invention, which has a plasma filter (2), two conductivity measuring cells (6, 13) and a haemofilter (9), do not come into contact with whole blood, so that re-use of the device (1) according to the invention is possible and use of biocompatible elements is superfluous. In addition, the measuring accuracy is increased because determination of the change in volume is based on plasma or plasma water instead of whole blood. <IMAGE>

Patent DE-3541804-A1 (DE)
Title: Process and apparatus for producing dry pellets
Inventor: ROOS HANS
IPC: B01J2/12
Filed: 1985-11-22
Abstract: A novel process for producing dry pellets from a slurry of fine-grained solids using a rotary pelletising drum (4) is proposed. In the pelletising drum, agglomeration and drying of the solids are effected simultaneously. Dry pellets produced at the outlet of the pelletising drum, which have a size less than a preset minimum size, are returned to the inlet of the pelletising drum. In order to dry the solids, hot gases from a hot-gas generator (5) are passed into the pelletising drum in parallel flow with the solids. In doing so, the gases removed from the pelletising drum may be recycled, at least in part, via the hot-gas generator or directly into the pelletising drum. The recycled dry pellets and the slurry of the fine-grained solids and, if required, the pelletising aids are mixed in a mixing apparatus (2) before being fed to the pelletising drum. The pelletising drum preferably has a three-pass drum which consists of three concentric rotating drums. <IMAGE>

Title: Outlet fitting for washbasins etc.
Inventor: MUELLER HANS-PETER
IPC: B05B1/16
Filed: 1986-12-18
Abstract: An outlet fitting for washbasins etc. has, within a central chamber having a lower first and an upper second valve seat, a valve element which can be moved axially backwards and forwards and has a valve stem extending upwards. The lower valve seat serves as a central water outlet while the upper valve seat serves as a peripheral, restricted water outlet leading to shower openings. A compression spring presses a push button arranged on the end of the valve stem bearing the valve element continuously upwards into the closed position of the valve element against the second valve seat. With the water inlet switched on and with the valve element in the closed position against the first valve seat, the backpressure of the water maintains the abovementioned closed position counter to the return force of the compression spring. A simple, easy-to-operate construction which is impervious to dirt is achieved by the fact that the push button is rotatable about the longitudinal centre line of the valve stem and is provided on the inside with at least one switching projection which, with the valve in the closed position against the first valve seat, can in each case be placed against a switching surface rising counter to the direction of actuation of the push button and held so as to be non-rotatable relative to the valve seats.
